A nurse is assessing a client's vital signs. Which vital sign reflects the number of times the heart beats per minute?

Answer: c. Place the bell of the stethoscope over the brachial artery.

Explanation: To obtain an accurate blood pressure reading, the nurse should place the bell of the stethoscope over the brachial artery, which is located in the antecubital fossa.

a. Inflating the cuff to 20 mmHg above the estimated systolic pressure may be appropriate for initial inflation, but the cuff should be inflated further until the radial pulse disappears, and then slowly deflated to obtain accurate readings.

b. Deflating the cuff at a rate of 2-3 mmHg per second is recommended to obtain accurate blood pressure readings.

d. Palpating the radial artery while auscultating for Korotkoff sounds is not necessary for accurate blood pressure measurement and may interfere with accurate assessment.

Answer: c. Faces Pain Scale - Revised (FPS-R) Explanation: The Faces Pain Scale - Revised (FPS-R) is commonly used for children who are too young to verbalize their pain intensity. It consists of a series of faces depicting different levels of pain intensity.

a. The Numeric Rating Scale (NRS) and Visual Analog Scale (VAS) require verbal or numerical expression of pain intensity, which may not be possible for young children.

d. The Wong-Baker FACES Pain Rating Scale is also commonly used for children and includes a series of faces to assess pain intensity, but the FPS-R is more widely used.
